ROLLER-FEED TABLE.

Specification of Letters Patent,

Patented Sept. 11,1906.

Application filed July 11,1905. Serial No, 269,175.

To all whom it may concern:

Be it known that I, JOHN IV. GooHER, a citizen of the United States, residing in the city of Johnstown, county of Cambria, and State of Pennsylvania, have invented certain new and useful Improvements in RollerFeed Tables; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. Y

My invention relates to the construction of roller-feed tables, with particular reference to those used in connection with metalrolling mills, and more especially to the construction of the aprons between the rollers, the journalbearings for the rollers, the side guides, and the manner of mounting them upon the frame or the side girder of the table, and means for securing the various portions together.

Although for the purpose of simplifying the description of my improved apparatus I have confined the illustration and specifications thereof to a roller-feed table as designed for use in connection with metal-rolling mills, I wish it understood that my in vention can be used in a feed-table for carrying or transporting any kind of material for which this style of apparatus is applicable.

Certain of the objects of my invention are to provide simple and efficient caps for the journal-bearings located in position by means of dowel-pins engaging with their extremities and the side frames or girders of the table and held in place by the prolongations of the aprons which extend between the peripheries of the two adjoining rollers, each of said aprons in turn being held in place by means of one large through-bolt passing through each end of same and through the main frame or side girder of the table.

A further object of my invention is to provide a construction such that the upper sur faces of the side frames, includin the prolongations of the aprons (but not t e removable side uides) lie in substantially the same horizontal plane, thus affording a smooth surface, over which wide plates or similar material can readily pass, and arconvenient plane on which to mount side guides in cases where these are necessary.

My invention also includes side guides for the table, which are used when transporting narrow material or edged plates, said side guides serving to maintain the alinement of said plates as they pass to and fro on the rollers.

My improved side guides are held in position on the main frames or side girders of the table by means of dowel-pins projecting from said side guides or from brackets secured thereto into corresponding holes in the side girders, so that the mere operation of lowering said side guides vertically will place them in position, and by raising them in the opposite direction they are at once removed without further manipulation.

Another and particular feature of my invention consists in the lower journal-bearing for the shaft of the roller, which bearing is made of cast bearing metalsuch as brass, bronze, or Babbitt-set in place in asubstantially semicircular recess provided therefor in the side frame and maintained in longitudinal position by means of an annular rib on the lower side of said j ournal-bearing, which rib fits into a corresponding groove in the frame. Each ournal-bearing is held in place by a cap which rests upon the upper edges of same, which cap in turn is held in place by the prolongations of the adjoining aprons, which bear upon the projecting flanges of said cap.

My roller-feed table with the side guides removed is adapted for use in conveying plates which are wider than the rollers of my table, while the addition of the side guides heretofore referred to adapts my roller-table for use in connection with the handling of universal or edged plates.

Referring now to the accompanying sheet of drawings,whichformparthereof, andinwhich like characters of reference designate like parts, Figure 1 is a side elevation of a part of my roller-feed table sufficient to show the con struction thereof. Fig. 2 is a corresponding plan view of the parts shown in Fig. 1. Fig. 3 is a transverse vertical sectional elevation taken on the planes indicated by thebroken line III III of Fig. 2. Fig. 4 is a partial ver. tical longitudinal section showing the crosssection of the central portion of an apron and a part of the adjoining feed-rollers.

In the various drawings, 1 indicates the main frames or longitudinal side girders of my feed-table, which are made, as indicated, in sections of convenient length, the opposite ones being secured together transversely by means of the through-bolts 3 and spaced apart at the proper distance by the separators or thimbles 2, while 4 indicates the bolts for securing the adjoining sections of the side girders together by means of their adjoining flanges 5.

At suitable intervals dependent upon the character and length of the pieces to be car= ried are located the journal-bearings 6, in which are mounted the shafts of the rollers 7, on the ends of which shafts are secured the bevel-gears 8, which are driven by the bevelgears 9., mounted on the driving-shaft 10. The journal-bearings for the roller-shafts are provided with caps 11, in which are the oilreservoirs 12, said journal-caps being also provided with projecting curved flanges or dust-shields 13, which extend within the shell of the roller and over the joint between the roller-hub and the bearing for same, thus excluding the dust therefrom. Dowel-pins 14 are provided,as shown, to locate the journalbearing caps in proper position on the side girders, said dowel-pins being mounted in holes provided in the projecting flanges 15 of the journal-caps 11 and extending into corresponding holes provided in the upper surface of the side girders 1. Extending between the peripheries of the rollers are the aprons 16, the upper surfaces of which are level and in a plane slightly below the upper portion of the periphery of said rollers, said aprons serving as guides and supports when necessary for the material passing to and fro on said rollers. The upper surface of the apron 'is located a slight distance below the upper portion of the periphery of the rollers, so that ust enough of the surface of said roller is exposed to properly support and traverse thepiece resting upon it. The aprons 16 are provided with projecting ends 24, which, as shown in the illustration, are of trapezoidal r form with horizontal upper and lower surfaces and with inclined edges. Said inclined edges are arranged to bear upon corresponding inclined edges on the projecting flanges 15 of the journal-caps 11, said aprons being held in vposition by means of large through-bolts 17, which pass through corresponding holes in the side girders or frame 1. This arrangement of the j ournal-caps, aprons with extensions, and one large through-bolt at each end of each apron securing both the apron and the journal-cap to the, frame, is an important and particular feature of my invention, as by means of this arrangement the usual large number of small parts is dispensed with. I prefer to make the through-bolts 17 so large that a man with a hand-wrench cannot twist them off, and as the parts are reduced to a minimum the change and repair of any portion rendered necessary by wear or breakage is facilitated.

As the operation of roller-feed tables of this character should be continuous, the simplicity of my arrangement and the ease with which repairs or changes can be effected conduce largely to the value of the apparatus.

It should also be noted that the arrangement of-the bolts 17 is such-that they are easily accessible, thus obviating the necessity for the repairman to go under the table or between the rollers. I

The aprons 16 are further provided with flanges 18, which fit in between corresponding projections on the side girders, as shown particularly in Fig. 3, thus serving to hold the various parts in proper relation to each other.

My side guides are composed of plates 19, which extend longitudinally on each side of the table, provided with brackets 21 and dowel-pins 20, which latter are mounted in corresponding holes, as shown, in the prolongation 24 of the apron and the side girders. Any side pressure brought to bear against the plates 19 of the side guides will not dislodge them from their position; but at the same time the construction is such that by lifting said side guides vertically they can be easily and quickly withdrawn when it is desired to roll or carry wide material, and they can be quickly replaced by a reversal of this procedure when narrow material is to be transported. I

The lower journal-bearings 6 are each provided with an annular rib 22, which is set' into a corresponding groove formed in the recess of the side girder.

In order that the lower portion of the journal-cap 15 may rest upon and hold the lower journal-bearing 6 in place, a clearance-space 23 is provided, so that the cap will rest upon the upper edges of the lower journal-bearing, and not on the side girder adjoining same. I make thelower ournal-bearings of Babbitt, brass, bronze, or other suitable material pre viously cast in molds and by means of my construction can readily replace a worn one by a new one when necessary.

Although I have shown the projecting ends 24 of the apron 6 as inclined, I do not limit myself to this particular arrangement, but may form the oint between the prolongation 24 of the apron and the projecting flange 15 of the journal-caps by a rabbet or right angle, oflset if preferred, the essential feature being that the adjoining aprons shall project over and hold the journal-cap in position.

In order that there shall be no obstruction above the surface of the aprons and their extension, I provide recessed openings for the reception of the heads of the bolts 17, and I also make the upper surface of the journalbearing caps 15 in substantially the same plane as that of the upper surface of the apron, thereby providing a flush construction of framework and its attachments, above which the rollers slightly project at intervals, This construction makes the table particularly applicable for conveying wide plates which project over the ends of the rollers, as may be readily understood.

'In the operation of my roller-feed table the plates or other material lie on the upper sur faces of the rollers 7, which are driven in either direction at will by their connection to the driving-shaft 10, which latter is provided with any suitable source of power. For handling wide plates the side guides 19-are removed, and on account of the flush con struction of the upper portion of the framework plates or material much wider than the rollers can be handled. The apparatus can thus be comparatively small and cheap, while at the same time effective. For handling narrow material or universal plates I prefer to place the side guides 19 in position, as shown on the drawings. As regards repairs, the principal features of my construction which require attention are the lower bearing-journals 6 and possibly the rollers themselves, which are easily and quickly replaced by unscrewing the nuts of the bolts 17, lifting a pair of adjoining aprons, and rem oving the journal-caps, thus allowing the rollers and the journal-bearings to be lifted and replaced.

- IVhile I have thus shown and described my invention, I do not limit myself to the exact details of the construction, but may modify the same or use equivalents thereof within its scope, as pointed out in the claims.
